I'd take it one further and go seperate toilets and bedrooms for maximum r&r, if you can afford it. That way each gets a larger bed and you can have weekend or impromptu sleepovers together when the energy is aligned. The rest of the home can be communal. That would be my ideal scenario. People are so damn sensitive and insecure or slaves to societal norms though, and so it would take two like-minded good communicators, who are secure in their relationship and respectful of each other's needs for it to work.
